I am trying to access perforce sitting on remote machine(I know its IP and port) using command line. I know p4v command is used to run perforce but it runs perforce GUI and not command line.
Why I want this because I want to run some commands(similar to sync) on remote host perforce. These command provides so many features which I can get in GUI.
I heard some p4 settings had to be done for this. I tried this link also but doesn't seem to work.
Can any one tell me how to access perforce for command line. I am looking for some step by step solution.
Thanks in advance.
As far as I know this is not possible, i.e., you cannot run p4 client commands on a remote machine.
If you are using Windows, then try PsExec from the SysInternals Suite.
psexec \\REMOTE_MACHINE p4.exe [g-opts] sync \\depot\path\...
Set the global options [g-opts] to override the remote machine environment, e.g. client, p4 server, port etc.
HTH,

I have to login to multiple hosts at one time, sometimes the number is around 20. The user and pass are same for all the hosts.
Currently to ssh onto these servers I have to run the ssh command manually in power shell and enter the password.
Is there any way I can just provide the servers list along with user/pass and open multiple PowerShell windows in one go? (help me if that can be achieved using ps script)
Sometimes I have to run the same command on all hosts, for that I am using mobaxterm. But again, in this tool as well I have to ssh to servers one by one.
Is there any single tool which can do both the magics (ssh to multiple hosts in one go and I can run commands parallelly)
here's my situation.
I'm running Cruise Control as a Windows Service and trying to get it to connect to a Mercurial Repository on BitBucket over SSH.
I'm pretty sure that everything's configured OK (PuttyGen, Pagaent, etc). I'm remoting onto the server using the same account that I am using to run the service and if I issue hg pull -b ssh://#bitbucket.org// from a command line everything works. I added -v to the ssh configuration in mercurial.ini and I can see all of the steps that are taken.
If I run CC.NET from a command prompt then it builds fine. In the console window I can see the same logging from the SSH operation.
However, if I run CC.NET as a service (using the same user account that I'm logged in on) the call to BitBucket times out. I can find no way to work out why either. The build log doesn't help and neither do ccnet.log or ccnet.trace in the temp directory. I was expecting one of them to contain the logging from the SSH operation, but they don't.
Can anyone help? Is it that running as a service prevents it from connecting to Pagaent (I've started Pagaent by adding it to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run). When I did the pull from the command line I had to OK a dialog, but only once. Is it waiting on the same dialog now that it's running as a service?
Getting close to my wits end here.
Thanks
I did get it working in the end. The trick was to create the public key without a passphrase. When running as a service the solution has to be completely non-interactive and the passphrase option with pagaent.exe just isn't.
Here are the steps:
Use PutTTygen to generate a secure key WITHOUT a passphrase. If you really do need one then you can add it to the mercurial.ini file, but defeats the point for me as it's in plain sight anyway.
Copy a mercurial.ini to two locations: C:\Windows\System32\config\systemprofile and C:\Windows\SysWOW64\config\systemprofile. Probably only one of these was really necessary, but I didn't have the time to experiment. The first is the home directory for the system user when running 64 bit apps, the SysWOW64 location for 32 bit. Make sure that if you do the same as me then keep both files in sync - or go one further and work out which is the correct location.
Add something like this line under the [ui] key in both files:
ssh = "D:\Program Files\TortoiseHg\TortoisePlink.exe" -ssh -2 -C -batch -v -i "[Path to your ppk file]"
Add the passphrase to the end of the command if one was created in step 1.
Make sure that TortoisePlink.exe is specified, not Plink.exe. They should both be in the same directory.
Download psexec from http://technet.microsoft.com/en-gb/sysinternals/bb842062.aspx
Run d:\PSTools\PsExec.exe -s -i cmd.exe. This will open a command line as the system account in interactive mode.
Now do an hg pull, or hg clone or whatever.
A dialog should pop up with a confirmation message. This is a one time thing and the reason that you have to do the PsExec step. OK the dialog.
Now cc.net should be able to be run as a service under the local system account using SSH!
I have a perl script that should execute on the log files in the remote server from my local desktop. Could some one suggest me best approach.
I used Net::SFTP but there is a problem with installing SFTP package from CPAN. Is there any good package available in Perl to do this functionality?
Can you tell me whether the following steps are fine?
Open SFTP connection with remote server
execute the perl at remote location from the established connection..
Any sample code for this?
If you mean that the Perl script is on the remote unix server and you want to invoke the Perl script from your local machine, then you can ssh into the remote unix server and then once you are connected, call your perl script using perl yourscript.pl.
If you mean that the Perl script is on your local machine and you are dealing with log files on the remote server, then it would be more efficient to have the Perl script located on the remote server that stores the logs, and invoke it in the way described in the above paragraph.
I'm not clear exactly what you are trying to achieve but if you just want to execute a Perl script on a remote server you may want to look at software specifically built for remote server management.
Tak is one such piece of software but it's quite new and a bit lacking in documentation.
Rex is a more mature, it would seem, piece of software for remote server management.
Both of these should allow you to run commands locally that perform actions remotely on your servers. I wouldn't have thought you'd need to do anything with SFTP and would think you could do it all with those or hand-rolling something with commands over SSH.
Instead of Net::SFTP, try using Net::SFTP::Foreign or, if you want to run commands on the remote host via SSH, Net::SSH2 or Net::OpenSSH .
I use to navigate my remote servers with ssh. Sometimes i would like to download a file to open in my computer.
But the only way i know how to do it is to open a new command line window and use scp from local to remote.
is there a way to do this directly from the ssh server?
like a command that know my current ip so can set up everything automatically?
(wonderful would also be to do the upload in such a way...)
There is no easy way to do it - I used ssh & scp many years the way you just described. But, you may configure ssh & scp in such a way that they don't require password each time, which is very comfortable! For this, you need:
generate keys by ssh-keygen - they can be also passphrase (= password) protected
copy the keys to remote machine to ~/.ssh/authorized_keys
And then, each time you start a session, you run ssh-agent and ssh-add. You just enter the password once. And then you can just run scp/ssh many times, from scripts, etc., without the need to enter the password each time!
I don't remember the exact way how to configure all this, but have a look at manpages of all those useful tools! Many things can be automatized by placing them into ~/.bash_profile or ~/.bashrc files.
I found this while trying to answer your question for myself:
https://askubuntu.com/a/13586/137980
Just install zssh and use Ctrl-# to go into file transfer mode.
I would like to be able to use Matlab-mode (matlab.el) to run a matlab shell. The only problem is, Matlab is located on a remote host. Is this even possible? If so, please explain. I'm currently playing around with tramp but to no avail.
Thanks.
I just tried using the emacs matlab mode through ssh, no problem
had to make a script which loads matlab, couldn't just specify the command in matlab.el
so:
/home/second/remoteMatlab:
#!/bin/bash
ssh orac matlab -nodisplay
where orac is the host which has matlab. you can pass commands to ssh here. i use ssh config and key authentication so only need the hostname here
in matlab.el, find
(defcustom matlab-shell-command
and set to eg
(defcustom matlab-shell-command "/home/second/remoteMatlab"
I am not 100% sure what you are doing, but this seems possible. If
you use Tramp (or sshfs, my personal choice) to edit a script on a
remote machine, you will be able to run it on that remote machine. If
you have a *shell* buffer open, it can easily be ssh'd to that remote
machine. If you are doing something REPL-like where emacs sends input
to this buffer that's connected to a process over ssh, it should still
work. If it is communicating with a remote process over a socket, you
can use ssh forwarding to make the socket appear local.
Anyway, there is not much gap between local and remote, so this should
all work out.
Finally, to toe the (GNU) party line... have you tried Octave running locally?
#Yotham : I can't comment yet on earlier answers, but your problem (Script working, malab-shell command in emacs not) may be due to the fact that you didn't delete/rename your matlab.elc file?
This way emacs never gets to know of the change since it prefers .elc over .el files for speed.
Resolved the same issue for me.
cheers
